HTML5 tags, metadata and microdata

I moved the JavaScript-enabled XHTML+RDFa home page for Aule Browsers to HTML5 today.  About half of the Dublin Core metadata was lost in doing so, as was Common Tag for Freebase.  All that was gained was the addition of Schema.org microdata.

Whatwg.org appears to have little sympathy for RDF where it is used.  There is a tendency to mistake RDF for one implementation in XML. Is that the source of this conflict? I see very little sign that Schema.org and microdata are a step towards the semantic web - and HTML5 itself offers as semantic markup such gems as "section" and "article".

The present deficiencies of the types offered by Schema.org seem to reflect geek mentality. poem is missing.  Language sprawls across natural language and programming language.  Just find a peer-reviewed linguistics article that argues for Python as a language and which article is then referenced with approval by a linguist ranked in the top twenty in that branch of science in a published book on his or her own specialty.  Oh, yes, "semantics".

Just try to start a dinner conversation on a blind date with a non-geek with

def nonsense()
WHITESPACE WHITESPACE pass

Pass the salt?

Where is that Pimsleur CD for Perl, lingua franca of the web ...

Sorry, but was that the punch line, or did you leave off a parenthesis?
XML-me, I missed a bracket when I removed lint from my one sport jacket.

That w3.org is not in the grip of Microsoft is no great consolation if it now guided by Google.  I mean,
(Google + (Bing + Yahoo!))  or, in summation, search for content trumps content.

My vote is for rich content; let the search engines be the ones who play catch-up.
